  1. Looks like we could have a shot at some strong single-cell convection in the late afternoon and evening in the NYC metro. Great MLCAPE of over 2000 with insane SBCAPE as well as a very moist surface, but the minimal shear in the lower levels of the atmosphere will limit the severity of these storms, most likely. Could be an interesting evening.
  2. Based on the last run of the HRRR, it looks like we could actually have a pretty potent severe weather setup this afternoon. Decent SBCAPE of around 1500, but the circular hodograph is really what sells it; there’s going to be great shear up to about 4-5km, which could lead to some more cyclonic cells to develop. The primary threat would be strong winds. The big caveat here is the amount of heating we’re going to get before the storms move through in a few hours. I don’t see KEWR getting up to 89, as they’re only at 82 right now. However, the wind profile is such that we wouldn’t need too much CAPE to make storms severe. We’ll have to see if the clouds cooperate. If they do, some severe storms would almost definitely develop.
  3. Just the final kicker for this garbage winter: a sick pattern... in May.
  4. I haven't posted my thoughts on the upcoming pattern in a while, so here goes. I'm actually very optimistic about the state of affairs entering February for a variety of reasons, the most prominent ones being the superposition of the polar and subtropical jets and the Pacific jet extension. As of now, the pattern is pretty awful for snow due to a Pacific intrusion because of a strong, zonal polar jet. This has lead to a relatively snowless pattern with highly positive temperature anomalies throughout the CONUS. However, as we enter the 5 day range, the pattern will begin to shift as the Pacific jet extends. The ageostrophic flow in the left exit region of the jet streak will force an Aleutian low; this will then lead to a more meridional flow over the W US and displace some of the cold air locked over Alaska. The most important aspect of this pattern is the superposition of the STJ and the northern stream, as this will provide ample phasing opportunities as we move into February. The threat next weekend is a prime example of this feature. The Pacific jet looks to remain extended for the long-term, and this will lead to colder than average temperatures over the E US. Although there is still a highly positive EPO, the colder air from Alaska is still accessed via the +PNA. The STJ is still open for business during this time period; that feature along with the cold will provide ample storm opportunities from next weekend onward.
  5. Personally, I think one of the more important factors is the system that pushes through before the SWFE. It has begun to trend in a more amplified direction in the last several runs: The heightened amplification of this feature leads to more CAA behind the system along with a more favorable NW-SE tilting of the 500mb flow. This, in turn, leads to a more favorable antecedent airmass for the SWFE: This system should be monitored closely. If it ticks more amplified yet again, then expect to see a colder run. This could be offset by a more amplified SWFE, but the lower heights in ahead of it due to the heightened CAA argue otherwise. Let's see how the 12z GFS plays out.
  6. The 06z NAM, yet again, is more amplified and farther west, promoting higher heights over the EC. This should make another favorable jump.
  7. GFS actually looks a bit more amplified with higher heights out front than the NAM through 12:
  8. Part of the tick north is also due to vastly increased heights across the entire NE US, which is due to lessened confluence in SE Canada, less influence from the lobe around Michigan, and a slightly more amped, farther west trough. Again, it’s a big change for 24 hours out.
  9. Wow, this is a really big tick given the short lead time. The trough is certainly more amplified and there’s more PVA as a result.
  10. WOW. This changes everything. Amazing FGEN forcing along with an extremely vigorous 500mb vortmax. Let’s see what the GFS does.
  11. The GFS OP is actually on the eastern edge of its ensemble spread, which has actually moved farther west from 18z. This is mostly in part to the entire trough/ridge couplet being more amplified from 18z:
  12. Hey, I mean considering it’s our only decent shot for like 10 days gotta hop on it haha. Could be a nice little event but we’ll obviously have to see over the next few days.
